The Sony RX10 has the same 20mp sensor as the Sony RX100 II that is well thought of and it has an equivalent 24-200mm f2.8 Zeiss lens. Having a package that includes the equivalent of a 24-70mm f2.8 and 70-200mm f2.8 makes the $1200 price easier to take.

You can't change the lens on the RX10, but a lot of m4/3 people would be quite happy, I think, even if all they had were the 12-35mm and 35-100mm for their m4/3 camera.

I have read that the zoom-by-wire is poor because turning the zoom ring causes the focal length to change very slowly. Maybe that can be fixed in firmware? Still, this looks to be a very interesting camera. It isn't very small, but I can imagine that for some people this could be enticing. More dof, of course, than FF or APS-C and slightly more than m4/3, but that isn't a big deal for everyone.

I could see that some people might have an m4/3 body to use with a couple of fast single focal length lenses and the RX10 instead of buying the expensive 12-35mm and 35-100mm lenses.

How does the shutter latency, AF performance and burst performance compare to an M4/3 camera?In other words, is the shooting performance more like an interchangeable lens system camera, or rather, like a high end point and shoot?

Are there a high quality wide and tele converters for the lens? 24mm is not wide enough for me nor is 200mm long enough for this to be my exclusive camera.

This camera is BIG: It weighs 29 ounces - that's twice the weight of my E-PL5 with a VF-2 and a pancake prime or kit zoom on it. I agree, if I were to include the extra telephoto zoom, things even out, but it's simply NOT a small camera.

The lens appears to be impressive, but my investment in it would be lost when the body/sensor is no longer competitive. If I paid $700-800 or so for an equivalent lens that I could keep for more than one generation of camera, it's a better deal in the long run.

Could you point me to an equivalent lens or lenses that covers a 12-100mm F3.7 range for $700-800 preferably $700 I am Scottish after all

All in all, it could not replace my system interchangeable lens cameras. I'd rather have them, and keep my Panasonic ZS8 superzoom pocket point and shoot with an admittedly slower 24-360mm lens and smaller sensor - which, BTW, I paid $60 for used on ebay.
